This product is used extensively in Great Britain and also is sold in Canada. I wasn't aware of any sales here in the US until I Googled 'em and found that they have finally entered the US market.

I used to be heavily involved in buying/selling vintage British sports cars and had heard nothing but praise for this stuff from my business contacts in Europe. Now that they sell the product and tools to apply it I may just buy some and test it out on my F350.

Waxoyl Waxoyl 120-4 for Cavities - Waxoyl USA

 

Looks like good stuff. My truck sure could use some.

 

Don't know how expensive that is, but in the airplane world, ACF-50, Corrosion-X, and Boeshield are the big names. Boeshield was developed by Boeing. I believe all three are approved to treat military aircraft.
Corrosion Treatment from Aircraft Spruce

 

Aircraft Spruce always has cool stuff and not just for airplanes.

I think a gallon of Waxoyl is about $170.00 plus you need the applicator. A few years ago my son bought a new pick-up and found an outfit across the river from Detroit that charged $800.00 to do a complete job on his truck. So if you bought the tools you'd save some $$$ even buying at retail.

My F350 is about 99% rust free so it might be a good idea to try to keep it that way. I didn't drive at all this winter and I plan on keeping it out of the deicers as long as I can.
